Airless spraying

Posted on by .

Airless spray painting can save time and money when painting large areas. Here are some great tips on airless spraying

airless sprayer• Keep the gun in a position that is square to the surface.
• Have the gun at an equal distance to the surface, moving the gun across or up and down the surface steadily.
• Keep moving the gun at a consistent speed to conserve paint and give even coverage. Also helps avoid runs and sags in the paint.
• Move the gun in a flowing fashion movement without hesitation.
• Spray alternately from right to left and left to right.
• Begin movement of the gun before pressing the trigger.
• Release the trigger before movement of the gun ceases.
• Hold the gun closer to the surface to deposit more paint on the surface and produce a narrower spray pattern. Hold the gun farther from the surface to produce a thinner coat and a wider spray pattern.
• If  excessive paint and runs occur, change to a spray tip with a smaller aperture. If  coverage looks thin or you wish to spray faster change to a tip with a larger aperture.
• For best results apply at least two coats. Don’t try and get it perfect first time round.
• Overlap each stroke. When spraying horizontally, aim for the bottom edge of the previous stroke so as to overlap.
• On a corner or edge, split the center of the spray pattern. Spray vertically so adjoining sections have even amounts of paint.
• Avoid holding the gun at an angle, to avoid uneven coverage.
• On exteriors, work from ground to roof. Do not spray if the wind is excessive.
• Always be mindful of any surrounding objects which may be damaged by over spray. Nearby vehicles should be moved or covered and windows need to be thoroughly masked.

Repairing concrete

Concrete will expand and contract due to temperature changes and shifts in the weight distribution of the building. This movement can cause cracks in the concrete flooring.

  • General Repairs Use a repair mortar for repairs over 3mm wide and 5mm deep.
  • Fine Cracks < 3mm wide Use a fine crack repair mortar to fill
  • Surface Levelling  a self leveling repair screed will make a surface more even
  • Vertical Repairs Use a light weight vertical repair mortar to minimize sagging.


Surface preparation
Read the directions prior to use on all products. First, remove all loose material and rake out with a bolster or scraper to create an area that will take filling more easily. Make sure the surface is dry, if necessary prime surface before application of repair product.

Industrial Painting and Surface Preparation

Every now and again, a business or organization will decide to spruce up their premises by renewing its paint job.

While the room of a house can be redecorated using a simple paint brush, performing the same job on an office building, warehouse or tank container using the same tool simply isn’t possible. This is why it’s necessary to call in industrial painters. Industrial painters are professional painters with a wide range of tools, skills and experience, who specialize solely in the maintenance of premise appearance.

Surface Preparation

One of the things that make industrial painting different from regular painting is the amount of surface preparation required. Good preparation is key to a high quality, long lasting paint job, and this is especially true when the work undertaken will be up against the elements for the duration of its life.

Ways in which industrial painters will prepare a surface ready for use are by using:

– High pressure water jets to wash away dirt and grit
– Various abrasive methods to remove defective coatings and rust prior to priming and repainting
While both are highly effective, abrasive surface preparation methods will leave the area which is to be painted with a refreshed look about it. Rust will be reduced, as will any dirt that has accumulated on the building or object due to its years of work.


Many buildings, tanks or containers will have a coat of paint on them already. To ensure the next coat is smooth-looking and the job is finished to a high standard, this first coat will often need to be removed.

Qualified professionals will be able to do this in a variety of ways, depending on which way will best suit the job at hand. Rollers and paint brushers are an option, or for large surfaces spray coatings can be more cost effective
